Anyone with a JP wii able to go online in US?

I got a jp wii, and today bought a lan adapter. Can not get online with it though, been trying for hours. Has anyone found a way to do this? Please let me know

Can you please test with a wireless connection to make sure its not your lan adapter?

I’m not sure how to do that. Of course everything is in japanese. But funny thing is i followed http://www.nintendo.com/consumer/systems/wii/en_na/windows/connect_movie.jsp, and it gave me an update. But then when i tried to connect in TvC it gives me an error. At first i was gettting the serching green arrows, now just nothing. I am not sure how to check wireless function. Any help please
